Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed March 29, 1920. Serial No. 389,767.

To all whom it may come m:

lie it known that I, CLARENCE W. Ynrrnn, a citizen of the United States,residing at Alto. in the county of Kent and State of Michigan, haveinvented certain new and useful Improvements in Snowplows, of which thefollowing is a specification.

My invention relates to improvements in snow plows for use uponautomobiles, autotrucks. and kindred vehicles, and its objects are:First, to provide a snow plow that may be readily attached to, orremoved from an ordinary automobile or other kindred ve-- hicle; second,to provide a snow plow with which the snow may be taken from the highwayfront of the vehicle, and forced off to one side of the road, and,third, to provide a means whereby power generated in the vehicle may beutilized to force the snow, after being accumulated in the crib of theplow,

off to one side of the track being cleared of snow.

I attain these objects by the mechanism and arrangement of parts shownin the accompanying drawing, in which Figure 1 is a front elevation of apart of an automobile with the crib of the snowplow shown in sectiontodisclose the position and operation of the sidewise conveying elementsof the plow. Fi 2 is an elevation of the front end of the rig t handside of an automobile, showing the outlines of my devices in place, withthe distributing fan in position. Fig. 3 is an elevation of therelatively left hand side of an automobile with the near side wheelsremoved to enable me to show one means whereby the power generated inthe automobile may be utilized for driving the snow conveying part ofthe plow.

Similar numerals indicate similar parts throughout the several views.

In the construction of this plow the first step consists in forming acrib, 5, in which a rotary spiral 4 is mounted to revolve freely. Iplace an inclined shovel 10, having upwardly extending sides 17, bymeans of which the snow is forced upwardly and backwardly, as theautomobile advances, and is deposited in the crib, about the verticalcenter of the spiral 4 so there will be no danger of the snow becomingsolidly packed in the crib before it is carried lengthwise thereof andis thrown ofi by the rapidly revolving fan 6.

To mount this plow upon the automobile,

I prefer the use of a strong supporting frame, as indicated at 16, whichis properly secured to the frame of the automobile, 1, and the back ofthe crib should extend well upward, as at 2 to avert the danger of snowbeing thrown upon the hood that covers the engine. In the accompanyingdrawing I have shown a sprocket wheel 9 connected with the spiral shaft,and a larger sprocket wheel 11 mounted upon the hind axletree 12, with asprocket chain 14: connecting themto drive the spiral from the hindaxletree, as one of the many available forms ofconnection that may bemade for driving the splral.

After the snow has been carried to the relatively right hand end of thecrib 5 it is necessar to remove it as readily as pos-- sible, and orthis purpose I have provided a rotary exhaust fan 6. To have this fanwork efficiently, it is desirable that it should revolve faster than thespiral does, and for this purpose I have shown it as mounted "above thespiral shaft and as driven by a forced solidly upon the round whenplowing very heavy snow. 11 this instance I have shown the spiral shaftas upon the same plane with theaxletrees 12 and 13, but deem it well toplace it asnearly the surface to be cleared as is possible and not cometoo closely in contact with obstacles under the crib 5 or the incline10.

It will be readily understood that a considerable deviation, both as toconstruction and means of propulsion may be made in this device, withoutavoiding my invention.

What I claim as new in the art, is:

1 In a snow plow for use upon auto vehicles, a shovel mounted ahead ofthe vehicle and arranged to slide snowupwardly and backwardly as thevehicle advances, a crib mounted at the rear of the shovellaterally ofthe vehicle, a horizontally disposed revoluble spiral mountedlongitudinal y in the. crib, means for revolving the spiral from thepower that propels the vehicle, a spiral ezihaust fan mounted at thedischarge end ofthe crib at an incline upwardly from the lon itudinalplane of the floor of the crib, an means for propelling said fan forexhausting snow from the crib and elevating it as it passes through thefan.

2. In a snow plow for use upon'auto vehicles, a receiving crib, aninclined shovel for'carrying snow into the crib as the vehicle' movesforward, a spiral mounted longitudinally 1n the crib, means forrevolving said splral to move the snow longitudinally of the crib, meansfor forcin the snow out 15 of the crib to one side of t e vehicle andmeans for supporting the lower end of the shovel independently of itssupporting frame, when movin heavy snow.
